What Phew AI Tab is
A tab manager that runs in a sidebar rather than the browser's own tab strip. New tabs are grouped as they open, inactive groups collapse, and each page is analysed so a search can find it later by what it is about rather than by its title.
It is built for people who work with far more tabs than the browser handles well.
What you can do with it
- Group new tabs automatically as they open
- Collapse groups you are not using
- Search across open tabs by content rather than title
- Tag windows at the bottom to tell them apart
- Switch groups with a keyboard shortcut
- Keep separate spaces for different themes of work
- Pick up the same tabs on another device
Who it is for
- Researchers working across many sources
- People who routinely keep fifty tabs open
- Anyone who loses pages they meant to come back to
- Users who separate projects into separate browsing spaces
What to watch out for
- The official description says page analysis is saved locally, while spaces and workspaces are synced to a server: confirm which parts leave the machine before using it for sensitive browsing
- A browser extension that reads every page you open needs its permissions reviewed
- Grouping rules need a look now and then, or groups stop matching how you work
- Cloud sync means your browsing organisation sits with the provider

FAQ
What does it actually do?
It groups tabs as they open, collapses inactive groups, and indexes each page so you can search for a tab by what it contained.
Do I need to organise tabs myself?
Less than usual. New tabs are grouped automatically, though the grouping is worth reviewing occasionally.
Is my browsing data kept locally?
The site states analysis is saved locally, but spaces are synced to a server. Check the current policy before relying on it for private work.
